A Stretchable and Compressible Sensor is being developed for wearable electronics and soft robots

Every day, technology pushes the frontiers of what is possible and paves the path for greater greatness in the world. Because of this, the electronics industry has experienced significant technical improvements. Electronic things, such as wearable gadgets and soft robots, provide convenience while also reducing the amount of work required by humans. Furthermore, stretchy and flexible electronic components such as actuators, supercapacitors, and sensors, which may be used to improve the efficiency and productivity of these things, might be beneficial.

Chinese researchers have invented new sensors that are compressible and flexible.

Chinese researchers have recently created a unique compressible and flexible hydrogel strain sensor that may be used in a variety of applications. This sensor has the potential to be useful in the development of several soft technologies that have sensing capabilities.

Aside than that, the sensor is reasonably priced and simple to install. It is therefore an excellent choice for large-scale deployments as a result of this characteristic. The hydrogel has a stretching range of 366 percent and a compressing range of 70 percent, respectively. Furthermore, even at this rate, the best possible sensing capabilities were maintained for the whole experiment. As a result, it is ideal for extremely flexible electronic applications.

The sensor’s development is ongoing.

The sensor was created by evenly dispersing carbon nanofiber powder (CFP) in a polyvinyl alcohol (PVA)-based hydrogel, according to the researchers. PVA has been shown to be a good approach for the production of flexible electronics. This is due to the fact that it has mechanical qualities as well as the potential to biodegrade. The dispersion of CFP within PVA resulted in an increase in the electrical conductivity as well as the mechanical strength of the substance.

The sensors are capable of reliably identifying the movements of a flexible electronic user, such as bending or stretching of joints. It can also detect pressure changes in the body that occur when a person walks, which is an additional benefit of this sensor. Certainly, this represents a significant advancement in the realm of stretchy electronics. This achievement has the potential to pave the way for subsequent technical breakthroughs that will be entirely beneficial to the general public in the long run.
